Abstract: The invention comprises a patient positioning and/or repositioning system, such as a laying, semi-vertical, or seated patient positioning, alignment, and/or control method and apparatus used in conjunction with multi-axis charged particle radiation therapy. Patient positioning constraints optionally include one or more of: a seat support, a back support, a head support, an arm support, a knee support, and a foot support. One or more of the positioning constraints are preferably movable and/or under computer control for rapid positioning, repositioning, and/or immobilization of the patient. The system optionally uses an X-ray beam that lies in substantially the same path as a proton beam path of a particle beam cancer therapy system. The generated image is usable for: fine tuning body alignment relative to the proton beam path, to control the charged particle beam path to accurately and precisely target the tumor, and/or in system verification and validation.

Abstract: The invention presents an approach that uses plural separated foils to shape an ion beam so that the intensity density of hot spots in the ion beam is lowered. More particularly, plural foils are placed in close proximity to each other, wherein at least one foil intercepts a portion of the beam to strip a charge from ions in different portions of the beam at different times, and thus, shape the ion beam. At a basic level, the inventive approach places plural foils so that the distance between planes of successive foils is a fraction of the radius of curvature of the beam's cyclotron orbit.

Abstract: An apparatus which can neutralize charged bodies such as processed substrates for semiconductor devices and for flat display, free from electromagnetic noise, impurity contamination, and residual potentials. To process in a prescribed way a wafer (5) to be processed, the wafer (5) is, for example, moved from a pretreatment chamber (2) to a low pressure reaction chamber (3). In this case, a gas, which does not react on the wafer, such as nitrogen and argon, is introduced into the pretreatment chamber (2), and is kept under a predetermined pressure by a vacuum pump (15). Then, ultraviolet rays are projected in the pretreatment chamber (2) from an ultraviolet rays lamp (11) constituting a means for generating neutralization charges, and positive and negative floating charged particles (electrons and positive ions) are generated by exciting the atmosphere in the chamber (2). Since the charges are removed by projecting the ultraviolet rays from the outsides of a case (1) and the case (2) and moreover in a non-contact way, no electromagnetic noise is generated and the residual potentials are vanished too.

Abstract: An ion beam neutralizer (10). High energy electrons (40) are directed through an ion beam neutralizing zone or region containing an ionizable gas. As the high energy electrons collide with the gas molecules, they ionize the gas molecules and produce low energy electrons which are trapped by a positively charged ion beam (14). As high energy electrons pass out of the neutralizing zone they are deflected back to the neutralizing zone by a cylindrical conductor (30) biased to deflect the high energy electrons and an accelerating grid (50) for accelerating the electrons back through the beam neutralizing zone.

Abstract: A high current (0.2 to at least 2 milliamperes), low-energy (2.2 to 4 MV) ion beam is generated and is utilized to produce clinically significant quantities of medical isotopes useful in applications such as positron emission tomography. For a preferred embodiment, a tandem accelerator is utilized. Negative ions (202) generated by a high current negative-ion source (200) are accelerated by an electrostatic accelerator in which the necessary high voltage is produced by a solid state power supply. The accelerated ions then enter a stripping cell (212) which removes electrons from the ions, converting them into positive ions. The positive ions (218) are then accelerated to a target which is preferably at ground potential. For a preferred embodiment, the solid state power supply utilized to develop the required voltages is a cascade rectifier power supply (206) which is coaxial with the accelerator between the ion source (200) and the stripper (212), and is designed to have a voltage gradient which substantially matches the maximum voltage gradient of the accelerator.
